Product Details

I. Product Description

TH-23-553(Ⅱ) is a solvent-free, one-component coating PVC crosslinking agent. Its main component is polyisocyanate (T80), and it is used to improve the adhesion of substrates made from coated fabrics, woven fabrics, knitted fabrics, aramid fibers, and other textiles.

II. Product Characteristics

1. Improves the adhesion of PVC accelerated sol coating to substrates made of polyester or polyamide aramid fibers.

2. TH-23-553 is particularly active. In PVC sol coatings, it controls the duration of the sol coating and the substrate (i.e., the service life of the end product). Currently, the maximum controllable reaction time is 60 months, and the outdoor product service life can reach 90/60 months.

3. Applications: Suitable for the production of high-end products such as tarpaulins, canvas, inflatable cushions, inflatable boats, inflatable kayaks, and stretch fabrics.

4. This product exhibits excellent crosslinking characteristics and controllable effects on softness, tear strength, peel strength, and open time.

5. This product is particularly sensitive to moisture and acids. Therefore, it must be stored in the original container in a cool, ventilated place at 5-30℃. Shelf life is 12 months.

6. Stir well in the slurry before use.

7. It is best to add the crosslinking agent and stir evenly before the slurry (masterbatch) is put into the machine.

III. Physical Properties

Appearance: White or slightly yellow emulsion, almost colorless, transparent liquid.
